Connecting to a GTX 330 Mode S Transponder
To receive Mode S TIS traffic data from a GTX 330 transponder on
your GPSMAP 495, connect an available RS-232 OUT pin on the
transponder to the Data In pin on the GPSMAP 495. (You do not
need to connect the transponder to the GPSMAP 495's Data Out
pin.) Then, set the corresponding RS-232 output configuration on
the transponder to REMOTE + TIS and set the GPSMAP 495's
Serial Data Format to TIS In or TIS In/NMEA & VHF Out. For
more information, see the TIS section on
Transponder Installation Manual.

To output frequency data to an SL40 comm or SL30 nav/comm
radio, connect the Data Out pin on the GPSMAP 495 to the RxD
pin on the comm radio. (You do not need to connect the comm radio
to the GPSMAP 495's Data In pin.) Set the GPSMAP 495's Serial
Data Format to TIS In/NMEA & VHF Out or Aviation In/NMEA
& VHF Out. For more information, see the VHF comm section on
page 139 and your nav/comm radio's installation manual.
